This image of Mimas was acquired by the Voyager 1 spacecraft on November 11, 1980 from a range of 425,000 kilometers (264,000 miles). The large crater on the right limb is named Herschel. It is 130 kilometers (80 miles) wide and one-third the diameter of Mimas. Herschel is 10 kilometers (6 miles) deep, with a central mountain almost as high as Mount Everest on Earth. This impact probably came close to disintegrating the moon.
